Fatigue is probably based solely on the PSD results (S-N curve usually assumes some mean stress) so there's no combination needed for that. If you have an S-N curve Mechanical will compute Fatigue damage or life for you.
Adding SEQV in EXCEL gets around the sign issue. You could do something similar with SUMTYP,PRIN in the APDL POST1 module.
